The Australian beauty oozed Old Hollywood glamour as she posed in a strapless black gown with a sweetheart neckline

Australian supermodel Miranda Kerr turned heads at the Breakthrough Prize red carpet event in Los Angeles alongside her husband Evan Spiegel. Looking like she could pass for someone half her age, the former Victoria's Secret Angel radiated Old Hollywood glamour in a stunning black gown with a sweetheart neckline. Miranda complemented the figure-hugging dress with a diamond necklace and matching earrings, and sported a chic chignon that accentuated her brunette tresses. She finished off the look with a bold red lip, making for a true vision of elegance.

Miranda, who is about to hit her 40th birthday milestone, maintains her youthful appearance by eating healthy and remaining committed to organic and wholesome foods. As she said in an interview with E Online, "The first step is eating healthy. I predominantly eat organic when I can. I eat extremely healthy because when I do, I have more energy." But the model does indulge her cravings from time to time, allowing herself a 20 percent splurge to avoid feeling deprived.

Miranda rose to fame after winning Dolly Magazine's modelling competition when she was just 13 years old. She went on to become Australia's first Victoria's Secret Angel in 2007, paving the way for her successful career in the industry.
